This loosely related sequel focuses on Steve Stifler's younger brother Matt Stifler, who is sent to band camp for the summer to avoid expulsion from high school by the counselor, Sherminator. Matt attempts to wire the camp with hidden cameras to turn it into the set for his own "Girls Gone Wild"-type video, but when he falls for his school band's director Elyse, his efforts to stifle his Stiffmeister ways will surely meet with hilarious results.

The story follows Mitchelle "Mitchie" Torres (Demi Lovato), an aspiring young musician who is hoping to become a professional singer. Mitchie wants to go to a music camp named "Camp Rock".

The original American Pie characters have moved on, except for Sherman and Jim Levenstein's still understanding dad. Steve Stifler's little brother Matt wants to join his brother's business (the original Stifmeister has hit it big producing Girls Gone Wild videos) and after everything Matt has heard from Jim's band-geek wife Michelle, he plans to go back to band camp and make a video of his own: Bandies Gone Wild!

A pair of horny college guys get summer jobs at a sexy cheerleader camp.

When a street smart "goth girl" (Roxy Vandiver) is forced to attend cheerleader camp as part of her rehabilitation from a juvenile correction facility...

Mitchie Torres (Demi Lovato) cannot wait to return to Camp Rock so that she and rock stars Shane Gray (Joe Jonas), Nate (Nick Jonas) and Jason (Kevin Jonas) can spend the summer making music and having fun with their friends. When they arrive, however, she discovers that Camp Star, a slick new camp across the lake, has lured many campers and instructors away, threatening the very existence of Camp Rock. Tess Tyler (Meaghan Jette Martin), the diva of Camp Rock, returns, but soon ditches the camp for Camp Star. Meanwhile, Nate and a girl from Camp Star, Dana Turner (Chloe Bridges), fall in love, and struggle to be together as their own camps fight. To make matters even more difficult, Camp Rock challenges Camp Star to a musical showdown to decide which is the better camp and has the right to remain open. Shane and Mitchie kiss.

Matt Stifler, the younger brother of the legendary Steve Stifler, who made it big as Hollywood porn-producer and shamelessly ignores the idolizing kid brother, may claim the title of Stifmeister as his heritage, but even for his horniest mates hes little more then a bad joke. When Matt alone gets caught red-handed for a prank with the school bands instruments, present high school counselor Sherman Sherminator finds great pleasure in taking revenge on him for the misbehavior Steve excelled even worse in, so instead of expelling the little prick, he condemns him to take part in band camp at Great Oaks, where Jim Levensteins still understanding dad is filling in for the feared problem counselor. As there are plenty of girls in the competing bands, Matt hopes to turn his (mis)fortune around by smuggling in camera equipment including a robot to shoot saucy, clandestine material for his counterpart to Steves hit video "Girls Gone Wild", an at least as revealing Bandies Gone Wild. Matts nerdy, yet also horny roomie Ernie was originally confined to the closet, but is promoted to assistant-producer when he proves himself an invaluable technician. Things get complicated as Matt becomes romantically involved with Elyse, his own school bands director, whose ambition is to beat haughty five-fold winner Brandon Vandecamp -son of a famous, rich father- as band music composer and thus win a good shot at a scholarship for an exclusive music school. For her sake Matt turns musician (on the trivial triangle by her decree, bagpipes in surprising scenes) and proves his leadership skills, but courting a decent girl just doesnt square with voyeurism...
